Analyses of reactor coolant flow rate decrease events using the KEPRI methodology

KEPRI is developing the in-house methodology for non-LOCA safety analyses based on the codes and methodologies of vendors and EPRI. To verify the feasibility of the methodology, reactor coolant flow rate decrease events have been analyzed at the standpoint of RCS pressure. Furthermore, to assess the important parameters to RCS pressure, the sensitivity analyses have been carried out over some parameters such as reactivity feedback, reactor coolant temperature, and reactor coolant pressure. The results of these analyses have similar trends comparing with those of FSAR 15
